It is a pendulum that had been swinging since the 1970s, when Hollywood and then British TV drama started to disrobe and feign explicit sexual intercourse, and the past decade, when simulated (and un-simulated) sex returned to our screens with a vengeance.Indeed, an average episode of E4's Skins, in which sixth-formers indulge in oral sex as casually as former generations of schoolchildren might have sucked on cigarettes behind the bike-sheds, would have had Mary Whitehouse spinning in her grave.
"Marlon said to me: 'Maria, don't worry, it's just a movie,'" recalled Schneider in 2007, 35 years after her mock lubrication and four years before her death.
"But during the scene, even though what Marlon was doing wasn't real, I was crying real tears.
I felt a little raped."Such impromptu exploitation is unlikely to happen today, says Harry Bradbeer, veteran TV director of risk-taking dramas such as This Life, Sugar Rush and BBC3's current lesbian saga, Lip Service.
"You have long conversations [with the actors] about roughly what you think the scene is about, because every sex scene, if it's meant to be there, must have something to say."This initial conversation won't take place at all, of course, if the artist has a no-nudity clause in their contract – an arrangement more common in Hollywood than in Britain.
Andy Garcia, Julia Roberts, Scarlett Johansson and Sarah Jessica Parker are reportedly among those who refuse to be filmed naked, while Charlize Theron, Neve Campbell and Sharon Stone insist on a "nudity rider", a contract that gives the actors the final cut of their love scenes.
For most actors, however, faking sex is a necessary evil."If I never had to do it again that would be the best thing," says Claire Foy, who simulated physical passion with Sam Claflin in BBC2's recent White Heat, and with Anna Maxwell Martin in the BBC2 adaptation of the Sarah Waters tale The Night Watch."You're worried about what the other person is feeling, you're worried about what the crew are thinking, whether they're really uncomfortable, whether you're uncomfortable.Sometimes you watch a sex scene in a movie and laugh at the fact they aren't even properly aligned! It was a dirty job, but someone had to comb through the history of cinema to find those times when everyone swears the movie stars were actually having sex while filming!From the urban legends of unsimulated scenes to the rhythm method acting admitted by the stars themselves, we found all the sinful cinema you can handle!CLICK HERE to see the gallery "Stars Who (May Have) Had Sex FOR REAL In Movies!
